An extensive debate between the Free Thought reformer Bradlaugh and the Christadelphian Roberts, who rather puts his thumb on the scale in the conclusion. (Though in fairness, Roberts notes he offered Bradlaugh the chance at summation as well—”but Mr. Bradlaugh has other means of letting his friends know his mind, of which he will, doubtless, avail himself should he consider it necessary to take notice of anything appearing herein.”).
